void gdk_frame_clock_request_phase ( GdkFrameClock* frame_clock, GdkFrameClockPhase phase )
Asks the frame clock to run a particular phase.
The signal corresponding the requested phase will be emitted the next
time the frame clock processes. Multiple calls to
gdk_frame_clock_request_phase() will be combined together
and only one frame processed. If you are displaying animated
content and want to continually request the
GDK_FRAME_CLOCK_PHASE_UPDATE phase for a period of time,
you should use
since this allows GTK to adjust system parameters to get maximally
The phase that is requested.
